Subject: [PATCH AUTOSEL 6.3 06/30] ASoC: codecs: wcd938x-sdw: do not set can_multi_write flag

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>

[ Upstream commit 2d7c2f9272de6347a9cec0fc07708913692c0ae3 ]

regmap-sdw does not support multi register writes, so there is
no point in setting this flag. This also leads to incorrect
programming of WSA codecs with regmap_multi_reg_write() call.

This invalid configuration should have been rejected by regmap-sdw.
